5 Claims. (Cl. 29-62) This invention relates to a glass jalousie construction suitable for use as a window or a glass wall structure.

The jalousie of the present invention comprises supporting posts, transparent panes, holders for the transparent panes, and an operating means. The posts may serve as wall studding or may be attached to frame rnernhers at opposite sides of the window opening. The posts and operating means are the same for jalousies of all sizes and the holders may be used with panes of any length so that the jalousies of any desired size may be built by simply cutting the panes to the proper size and assembling them with the holders, posts and operating means. The holders fit on the ends of the panes and are formed to provide sockets in which the ends of the panes fit, the sockets being formed with an enlargement to receive an elastic pane retaining block of rubber-like ma terial. Each holder is provided substantially midway between its ends with a pivot that projects into bearing openings in the posts that are so positioned that adjoining edge portions of the slats overlap when swung to their closed positions.

The operating means comprises an upright actuating bar that is connected to parallel pivots carried by superposed holders at one end of the jalousie. Each of the holders has an inwardly projecting lug which carries a pivot pin disposed parallel to the slat pivot and adapted to enter a bearing opening in the actuating bar. To facilitate the attachment of the actuating bar to the slats, each of the pivots engaging the bar is provided with a laterally projecting lug adjacent its outer end that is p0- sitioned to enter a slot at one side of the bearing opening of the bar when the slat is in a predetermined angular position. The slots in the actuating bar and the lugs on the pivot pins are so arranged that the slats must be swung past their full open horizontal position in order to aliuc the lug of the pivot with the slot in the actuating bar.

A suitable crank and lever actuating mechanism is attached to the vertical bar and this actuating mechanism imparts an angular movement to the slat which is somewhat less than that required to aline the lugs with the slots of the bar, so that it is necessary to disconnect the actuating bar from the actuating lever in order to detach the actuating bar from the slats.

The holde s are so formed that they permit adjoining edge portions of the panes to have face to face contact throughout their length when in closed position and the posts and holders have projecting ribs that have side faces in contact throughout the spaces between the slot pivots when the slats are in closed position so that the pane holders and posts provide a weather-tight closure when the slats are in closed position.

Objects of the invention are to provide a glass jalousie construction that is inexpensive, that can be quickly andeasily assembled, to provide a construction in which the panes, holders and posts form a weather-tight closure when the slats are in closed position, and to provide a construction in which the glass holders are provided with position. when the slats are in closed position so that the holders 2 amazes Patented May 17, 3%55 glass retaining means that is accessible for removal only from the interior of the building.

Fig. 10 is a fragmentary perspective view of the actuating bar.

In the accompanying drawings a jalousie is shown in which each of the slats is composed of a transparent glass pane i and holders 2 and 3 that are attached to opposite ends of the pane. The pane holders 2 and 3 are each an elongated member preferably a die casting of a light metal alloy such as an aluminum alloy formed on one side with a shallow socket in which an end of the pane fits and having an integral pivot 4 projecting from its opposite side. The pivots 4 are disposed substantially midway between the ends of the holders and are axially alined so that the slats can be mounted to swing about horizontal axes. The slats are supported between vertical posts 5 which may serve as wall studding or which may be attached to the inner faces of vertical window frame members. The posts 5, which may also be formed of a light metal, have vertically spaced bearing openings 6 to receive the pivots 5, these openings being spaced apart vertically a distance less than the width of the slats so that the edges of the slats overlap in the closed position thereof. Each of the posts is provided with inwardly projecting ribs 7 that extend vertically from opening to opening, each of the ribs being of a thickness less than the diameter of the bearing openings 6 and being in alinement with the axes of the openings.

Each of the holders is provided with ribs 8 and 9 which extend upwardly and downwardly from the pivots 4 to the upper and lower ends of the holders. The upper rib 8 is parallel to the lower rib 9 and the center planes of these ribs are spaced at equal distances from a plane that includes the pivotal axis of the slat and are spaced apart a distance corresponding to the thickness of the ribs '7. The ribs 8 and 9 are inclined at a small angle to the plane of the pane 1 to which their holder is attached so that the ribs 8 and 9 engage the outer and inner sides of adjacent vertical ribs 7 on the post when the slat is in closed The holders 2 and 3 closely overlie the ribs 7 and 3 and ribs 7, 8 and 9 provide a weather-tight closure between the end edges of the slats and the supporting posts when the slats are in closed position.

The holders 2 and 3 are of identical construction except that the holders at one edge of the jalousie are provided with means for attaching them to an actuating mechanism.

=3 As herein shown, the holders 2 are provided with integral inwardly projecting lugs that have laterally projecting pivot pins 11 at their outer ends, the pivot pins 11 being disposed parallel to the pivot pins 4. Each of the pivot pins 11 is provided with a radial lug 12 adjacent its outer end and these lugs serve to retain an actuatingbar 13 in place on the pivot pins. The actuating bar 13 is provided with bearing openings in the form of keyhole slots 14 which are adapted to receive the pivot pins 11 when the slats are swung past their full open horizontal position as shown in Fig. 7 of the drawings. As herein shown, the openings 14 are slotted at their bottoms and the lugs .12 are so positioned that they aline with the slots of the openings 14 when the slat is swung to the position shown in Fig. 7. The actuating bar 13 has a link 15 connected at its upper end thereto, the lower end of the link being connected to a crank arm 16 carried by a horizontal shaft 17 adjacent the bottom of the window opening. A gear segment 18 is formed integrally with the crank 16 and meshes with a gear segment 19 carried by a horizontal shaft 20 mounted in a bracket 21 attached to the interior of the building wall, the shaft 20 being provided with a suitable handcrank 22 by means of which it may be turned to open or close the jalousie.

The actuating mechanism is preferably so connected to the actuating bar 13 that the slats are not permitted to move far enough to aline the lugs 12 with the keyhole slots of the operating bar so that it is necessary to disconnect the bar 13 from the actuating mechanism when it is desired to replace a holder.

Each of the holders has a flat wall 23 forming the bottom of the pane receiving socket and engaging the end edge of the pane throughout its length. The pane receiving socket has an outer side wall 24 that is provided with a'flat inner face for engagement with the outer face of the pane 1. The socket has an inner side wall 25 that is formed to provide a space for receiving a pane cushioning and, retaining block 26 of a suitable rubber or rubber-like material. The inner side wall 25 has an inset upper end portion 27 that engages the outer face of the glass pane 1 and an integral portion 28 that is perpendicular to the end portion 27. 'The outer side wall 24 terminates short of the upper end of the holder so as to expose a portion of the pane for face to face engagement with the pane of the next adjacent slat and the inner side wall 25 terminates short of the lower end of the slat to expose a portion of the outer face of the pane adjacent its lower edge for engagement with the inner face of an adjacent pane as shown in Fig. 5.

The inner side wall 25 has a short flange 29 at its lower end that engages the lower end of the cushioning block 26 and a short flange 30 that engages the side face of the cushioning block to retain the same in the holder. The inner side wall 25 may also be provided with serrations 31 to more securely hold the cushioning block in place. The lower end portion 32 of the wall 23 is substantially flush with the inner face of the pane 1 and abottom wall 33 is provided for engaging the bottom edge of the pane and this wall also is substantially flush with the pane. The pane socketalso has a top wall 34 that engages the top edge of the pane and that is formed integrally with the walls 23 and 25. The upper portion 35 of the wall 23 is flush with the inner face of the pane 1 so that the ,slats have face to face contact throughout their length in their closed positions. The jalousie window of the present invention requires no weather strips to make it weather proof. As above explained, the holders and posts have interengaging ribs which provide closures between the edges of the jalousie and the supporting posts when the window is closed. The jalousie will also effectively exclude driving rain when in a partially open position. The interior faces of the posts 5 are flat and closely overlie the edges of the ribs 8 and 9 of the holders. The exterior faces of the holders 2 and 3 are flat and closely overlie the edges of the ribs 7. Consequently, the spaces between the edgesof the jalousie and the posts are effectively sealed against entry of water during a rainstorm when the slats are disposed at a small angle to their fully closed position to provide ventilation. The pane cushioning and sealing blocks 26 also serve as sealing members and make it unnecessary to maintain great accuracy in the cutting of the panes. In the event that one of the panes is a trifle short and does not snugly engage the holders, the sealing blocks which extend to near the top ends of the holders will provide a seal to prevent entry of water through the space between the wall 23 and the edge of the panel.

It is to be understood that in accordance with the provisions of the patent statutes, variations and modifications of the specific devices herein shown and described may be made without departing from the spirit of the invention.
